Great Little Practice Amp

If you’re looking for a compact practice amp, it really is hard to beat the Roland Micro Cube GX.

It comes loaded with an amp model for every situation, and weighs in at just six pounds.

This small and lightweight amp features a 3W amplifier section that drives a 5" speaker, so don't expect it to be loud, but it does have enough volume for solo practice.

And since it can run on batteries, you can use it virtually anywhere, making it a great mobile amplifier for guitarists who are always on the go.

It also helps that it comes packed with DSP features which include 8 COSM amp models, and 8 COSM effects, which allow for a wide variety tones.

It also comes with modulation effects (though to get different distortion profiles you will have to switch between amp voicings).

The controls on the amp are as follows: amp type, effect, delay/reverb, tuner, gain, volume, tone, and master volume.

The modulation effects on the amp and its clean channels are surprisingly good for its price.

The Roland Micro Cube GX comes with an AUX-In, headphone line-out, and an emulated line-out for recording.

Roland's 'Cube Jam' iOS app has a very low rating on the app store, however this is only an add-on and not required for the amp's general operation.

If you're looking for a long term practice amp with good enough flexibility in the sub $200 price range, then this is a good amp for you.

What Retail Customers Are Saying

Here is a summary of what verified customers are saying in their reviews at online retailers
Positives
  • Great for practicing
  • Surprisingly loud for such a small amp
  • Very portable - pop it in your backpack and carry your guitar at the same time
  • iPhone connectivity is a nice addition
  • The modulation effects are quite good, this includes Chorus, Flanger, Phaser, Tremolo
Negatives
  • Lack of Bluetooth is disappointing
  • The small speaker produces limited low-end frequencies
  • The iPhone app is unintuitive to use (it has very low ratings in the App Store)

Alternatives

Unfortunately this is very difficult to find new in stores these days. If you'd rather buy a new amp instead of a second hand one, then you'll have to decide which features are most important to you because there is no close analog.

  • Practice Amp - The Fender Mustang LT25 is similarly priced and has a good range of effects and amp models.
  • Battery Powered - The Yamaha THR5 runs on 8 x AA batteries and also has a good selection of effects and amp models, the drawback is that it costs a little more.

These videos provide good demonstrations of the various models, effects and sounds this little amp is capable of.
